BAY CITY, MI — A Bay City teen admitted in court to sexually assaulting a woman while on probation for sex offenses committed against other women.

Nicholas P. Johnson, 18, on Tuesday, Aug. 27, appeared before Bay County Circuit Judge Joseph K. Sheeran and pleaded guilty to single counts of assault with intent to commit sexual penetration, a 10-year felony, and failure to register as a sex offender. In exchange for his pleas, Bay County Chief Assistant Prosecutor Nancy E. Borushko agreed to dismiss a charge of third-degree criminal sexual conduct using force and a second count of failure to register as a sex offender.

Borushko also said she would not seek a habitual offender sentencing enhancement.

Regarding the failure to register charge, Johnson said he moved earlier this year and it had slipped his mind that he needed to register his new address with police.

Pertaining to the assault count, Johnson said that in February, he was at a female acquaintance’s house and put her hand down her pants. He initially told the judge that the woman told him to stop and that he did so.

Bay County Circuit Judge Joseph Sheeran said he did not find Johnson’s statement to be a sufficient basis for him to accept the plea. Johnson then conferred with his attorney, Kenneth Malkin, before stating to the judge that he did not initially stop his advances when the woman told him to cease.

Sheeran then accepted Johnson’s plea. He also informed Johnson that as he was on probation at the time his newer offenses, thereby violating his probation, he would be resentenced on his previous convictions.

Johnson was 15 in the summer of 2010 when he attacked two women on Bay City's Riverwalk. The first incident happened Aug. 1, when Johnson approached a 29-year-old woman near Veterans Memorial Park and tried pushing her down and sexually assaulting her. The woman managed to fight off Johnson, who fled on a bicycle.

The second incident occurred on Aug. 4, when Johnson attacked a 55-year-old woman jogging on the Riverwalk. As with the first instance, Johnson fled the scene on a bicycle.

Police arrested Johnson on Aug. 10 after his victims identified him. He was charged as an adult and later pleaded guilty to one count of assault with intent to commit sexual penetration. He was petitioned as a juvenile to be under the supervision of the Michigan Department of Human Services.

Circuit Judge Harry P. Gill is to sentence Johnson on all of his convictions at 1:30 p.m. on Monday, Oct. 14.
